2.  Push the [ENTER] knob to select the MOB position as the destination, or 

press the [CLEAR] key to only mark current ship’s position as a waypoint. If 
you select the MOB position as destination; 

 

• 

A full-screen radar, plotter or overlay (color model only) appears depending on 
the display in use. 

• 

The MOB mark “M” appears at the MOB position and a line runs between it 
and current position. This line shows the shortest course to the MOB position.   

• 

Range and bearing to the MOB position are shown in the MOB data box. 

 
To erase an MOB mark from the plotter display, 

you must first erase its 

corresponding waypoint because that there are normal waypoint and MOB mark 
at the same position. Place the cursor on the MOB mark, then press the 
[CLEAR] key followed by pushing the [ENTER] knob to erase the waypoint. Then, 
repeat to erase the MOB mark.
